Hi, i am trying to enable dma in Redhat 8 on my dvd drive, so i can
watch dvds. mplayer plays them, except that they are jerky when the dvd
has to keep reading, then pauses between reads. I tried adjusting cache
options for mplayer with no luck, and tried adjusting the speed of the
drive.
does anyone know why
|# hdparm -d1 /dev/cdrom
|
|/dev/cdrom:
| setting using_dma to 1 (on)
| HDIO_SET_DMA failed: Operation not permitted
| using_dma = 0 (off)
fails. the dvd drive is a fairly nice (panasonic?) dvd drive, that plays
dvds admirably in windows (when media player will let it...)
thanks.
Anton
